' BULL-RCPE PROTECTOR.

Specification of Letters Patent. 1

Application filed February 1, 1912. Serial N6. 674,694.

To all whom it may 00mm.-

,Be 1t known that I, PHILLIP A. SoHMUcK,

;a citizen of the United States, residing at Los Angeles, in the countyof Los Angeles andState of California, have invented new and usefulImprovements in Bull-Rope Pr'otectors, of which the following is aspecification.

- i This invention relates to improvements in bull rope protectors andshifters and it is an object of the invention to providea mechanism bywhich the usual bull rope of a well boring mechanism, may be lifted orshifted and held out of engagement with the tug wheel which is employedto drive it inoperating the bull wheel.

It is also an object of the invention to provide a lever mechanismadaptedto raise and hold the bull rope of a well operating mechanism,out of engagement with the revolving tug wheel when it is not desired tooperate the bull wheel,

In the accompanying drawing forminga part of this specification, Figure1 is a side elevation of a tug wheel, and a portion of a bull wheelbeing also shown in side elevation and as liftedfrom the tug wheel bythe improved mechanism forming the subject matter [of this invention.Fig; 2 is an edge elevation of'the tug wheel and adjacent band wheeldriven by the engine of the mechanism not shown, the bull rope protectorbeing shown in position. Fig. 3 is a t op'plan view of the said bandwheel, tug wheel and bull rope protector. Fig. 4 is a, detail View inend elevation of the bull rope protector showing two arms employed forlifting the bull rope. Fig. '5 is a detail view in side elevationof-t-he'modified form of bull rope protector shown in Fig. 4 and showingalso a rope for lifting the same.

The details and features of the invention will now be more particularlydescribed, reference being had to the said drawing in which indicates abull rope of the ordinary type employed in connection with the oil welldrilling mechanism. (3 indicates a bull wheel adapted to be driven bythe said bull rope, 7 a tug-wheel or pulley carried by an adjacent bandwheel 8 which is driven by a belt 9 extending to an'engine not shown.The tug and band wheels 7 and '8 are mounted upon a shaft 10 which isjournaled upon suitable pillars 11 in the usual manner.

T'he band Wheel 8 is ordinarily driven more or less continuously theengine and when the bull rope 5 is notibeing employedfor drivingthe-bull wheel it is either necessary to allow it to rubloosely upon thesaid: tug

wheel, or to haveianattendantgo around into the engine housing-andcloseto the rapidly movingband wheeland tug wheel and lift the bull ropeofl'. The present invention obviates this loss of time and danger andaifords means for shiftingthe bull rope from a position outside theusual housing built around the engine and the band wheel. In operatingthe bull wheel -6 also it .now usually: requires the shutting down ofthe engine teniporarilyto'place the bull rope upon the bull wheel andupon-the revolving tug wheel-7. a

The improved .mechanism forming the subject matter of this invention isadapted to suspend and hold the bull rope out of contact with the tugwheel when the bull Patented Sept. 30,1913. 1

wheel (3 isnotbeingoperatedand'to facili 'anism for effecting thispurpose 1 comprises a pivoted bar 12' which' is jourl'ialed'at itslowerend' upon a bolt- 13 secured to one of the pillars 11. The upperend of said bar 12 extends slightly ahove'the tug wheel 7 and isprovided within-n :arm14, which is journaled upoi'tthe said bar- 12aiidwsupported thereon at a proper h'eight-bymeans of an adjustablecollar 151 A set screw 1.6 affords means for holding the "said collaradj ustably in place: The 14 ie-formed with an'enlarg'ement or eye 17whichfits rather snugly upon the bar-12 so as not'to swing out ofposition ordinarily. Its engagement withthe bar, however, is such thatit can be forced to one side by the action of the bull rope whennecessary. Ordinarily the said arm 14, however, extends inwardly towardthe band wheel, over the periphery of the tug wheel as shown in Figs. 2and 3.

A thrust rod 18 is pivoted at 19 to the bar 12 and its outer free endextends outside the engine house (not shown) and is provided with a handhold 20. By pulling upon the hand held 20 when the parts are in theposition shown in Fig. 1 and-the arm 14 is holding the bull rope out. ofengagement with the tug wheel, the arm 12 may be rocked forwardly to theposition shown in dotted lines in said Fig. 1 so as to drop the bullrope upon the tug wheel. At this time the bull rope is also put upon theperiphery of the bull wheel 6"so that the said rope will communicatemovement from the tug wheel.

1 of the bull wheel the bull-rope 5 is drawn from its periphery, withoutstopping the band wheel 8 orthe tug pulley or wheel carried thereby.Then the arm 12 is formed to its upright position as shown in full linesin Fig. 1 so as to lift the said bull rope out of engagement with theperiphery of the tug wheel or pulley. In this position the band Wheel 8with the tug wheel or pulley 7 can continue its operation under theaction of the belt 9 and yet will not wear upon or engage the bull rope.Sometimes it is desired to start the bull rope in the opposite directionfrom that heretofore described, especially when the engine is reversedand the movement of the band wheel 8 is in an opposite direction. Insuch event the bull rope 5 is pulled upon so as to draw it a ainst thebottom of the tug wheel or pulley and since the bar 12 cannot moveoutwardly, be-

causeof the shaft 10, the arm l lwxll be' turned to one side by the bullrope, so as to be thrown out from beneath it and the bull rope will thendrop into place upon the groove of the pulley or wheel 7. It will thusbe apparent that the device is useful for holding the bull rope and forpermitting of'its being put in place again whenever it is necessaryto-drive the bull wheel.

As shown in Fig. 4 the construction of the bull rope lifting mechanismmay be. slightly modified and the outer end of the bar 12 may beprovided with a cross bar 22, the ends of which are provided withupturned standards or --end portions 23 upon which arms 24 are pivotallymounted, the said arms bein practically the same as the arm 14 heretoore described. By this construction the bar 12 may be made to supportthe bull rope at two points instead of at one for further insuring thecomplete disengagement of the said bull rope from the tug Wheel. In thisinstance also as shown in Fig. 5 a lifting rope 25 may be' employed andconnected with an eye 26in the ugperf" end of the bar 12 for lifting itinstea using the thrust rod 18 heretofore described, the said ropeextending to anydesired point outside the engine house. The action ofthe parts is ractically the same as already set forth an needs nofurther description.

\Vhat I claim is:

1. In a bull rope protector, the combination with a tug wheel and itssupport, of a bar pivotally mounted on said support and movable in aplane parallel with the periphery of the'tug wheel limited by itscontact with the shaft of said tug wheel, a stop adjacent said bar. tosupport said bar, and a contact arm slidably mounted on said bar,extending over the groove in said tug wheel, an adjustable sleeve toadjust and support said contact arm, and an operating rod securedintermediate said pivotal mountingjacent said bar to support saidbar,and a contact arm slidably mounted on said bar, extending over thegroovein said tug wheel, an adjustable sleeve to adjust and support saidcontact'arm, and means to swing said bar, whereby the bull rope islifted and held out of contact with said tug wheel by said bar engagingsaid shaft, and also supported. on said stop.

In witness that I claim the foregoing I have hereunto subscribed my namethis 20th day of January 1912.
